Context of Lesson:
This lesson will be on the second day of the unit following the introduction of the unit. During this lesson the students will be learning about covalent bonds. The students will be connecting their knowledge of electron configuration and Lewis Dot Diagrams to begin to understand how a covalent bond is formed. In this class I will be getting the students very involved by having student come to the board and work on problems.
Opportunities to Learn: Depth of Knowledge:
Level 1
Define the octet rule.
Draw a lewis dot diagram of compounds with 2-5 atoms.
Level 4
Apply the octet rule to a molecular compound.
Prerequisite Knowledge:
Bonding
Electron configuration
Valence electrons
Lewis Dot Diagrams
Periodic Table
Molecular Formulas
Nomenclature
Plans for Differentiating Instruction:
During this class many examples of Lewis Dot Diagrams will be done. I will be verbally going over the steps for the auditory learners; drawing the steps on the board for the visual learners; and will be having students come to the board to do examples which will help the kinesthetic learners because they will be able to move around.
Accommodations and modifications:
I can give some of the struggling students a step by step guide on how to draw a Lewis Dot Diagram.
Environmental factors:
The students will be sitting in their normal group seating.
Materials:
Periodic Table
Objectives:
Students will draw a lewis dot diagram of compounds with 2-5 atoms.
Students will define the octet rule.
Students will apply the octet rule to a molecular compound.
Instruction: Opening:
Talk about yesterday’s class and what we learned.
Reviewed some nomenclature and molecular formulas.
There are many differences in ionic and molecular compounds
We spoke mostly about properties; specifically boiling and melting points
Ask the student why they think ionic compounds and molecular compounds differ so much.
Get student responses.
The types of bonds.
I wonder if there was a way to see how covalent bonds occur...
Do you think you've made a sufficient case for learning about covalent bonds? You clearly think they are interesting. Why? What does know about the different types of bonds give a normal student? Does this difference explain differences in properties beyond boiling and melting? How do we use this difference technologically?
Engagement:
Review on electron configuration and Lewis Dot Diagrams of single atoms.
Do several with the help from students.
1 element from each column. Good.
Have students come to the board and do a few more.
Last example: a noble gas
Noble gases
Why are they called noble gases?
Don’t react.
Why not?
The Octet Rule.
How can we relate the Octet Rule to covalent bonding?
We saw some of this with ionic bonding.
Are you going to point out trends along the periodic table from your examples? Would it be worth showing some Video Period Table clips that talk about how various elements form compounds?
Draw water (H2O) on the board.
Have student draw a Lewis Dot structure for each atom.
How could this bond?
Demonstrate how to draw the Lewis Dot structure for the molecule than ask if it follows the Octet Rule.
Make sure to identify the unshared pairs of electrons and that the valence electrons react.
Do several more examples with the students help.
Give students a few to do on their own then have some write their answers on the board and discuss. Good. What will you do during this practice session? What will you be looking for as you walk around?
Closure:
Today we learned about covalent bonds and more specifically how to draw a Lewis Dot Diagram of a compound.
The bonds we learned about today were single covalent bonds. Tomorrow we will learn that there are double, triple, and coordinate covalent bonds.
Assessment:
There will be a short quiz in the beginning of the next class on drawing Lewis Dot Diagrams.
